• 📈 Scale control per post

  • Set resultLimitPerPost (1–500) to cap how many comments you collect per post, ideal for batch runs across many posts.

How to use LinkedIn Post Comments Scraper - step by step

1. Sign in to Apify.
2. Open the LinkedIn Post Comments Scraper actor.
3. Add your input under Posts:
   • In startUrls, paste one or more LinkedIn post URLs or activity/UGC IDs (e.g., https://www.linkedin.com/feed/update/urn:li:activity:7289521182721093633/ or 7289521182721093633).
4. Configure limits and filters:
   • resultLimitPerPost: Set how many comments per post to collect (1–500; default 10).
   • postedLimit: Keep only comments from the last 24h, week, month, 3months, 6months, or year (default any).
   • scrapeReplies: Enable to include nested replies.
   • profileScraperMode: Choose short (no profile details) or full (adds headline and profile picture).
5. Provide authentication:
   • liAt: Paste your LinkedIn li_at cookie for logged-in access. Without a valid li_at, LinkedIn requires authentication to fetch comments and the actor will likely fail.
6. (Optional) Set Proxy Configuration:
   • Leave default for direct connection, or enable Apify Proxy. The actor can automatically escalate to datacenter or residential proxies if blocked.
7. Click Start:
   • The run discovers the required query, builds a session, and fetches comments in reverse chronological order with built-in delays and backoff.
8. Download your results:
   • Go to the run’s Dataset and export as CSV, JSON, or Excel for downstream analysis.

FAQ

How many comments can I scrape per post?

You can collect between 1 and 500 comments per post using resultLimitPerPost. The scraper fetches comments in reverse chronological order.

Can it include replies to comments?

Yes. Use postedLimit and choose any, 24h, week, month, 3months, 6months, or year to keep only recent comments.

Yes. You can supply Proxy Configuration. The actor also handles session setup, random delays, exponential backoff on 429s, and can escalate from no proxy to datacenter to residential when blocked.
